PILOTFriXion Ball Erasable & Refillable Gel Ink Pens, Fine Point 0.7 mm, Pack of 3, Black, Blue, & Red

I have been using the FriXion line of products since I discovered some in a local stationery store. It is a wonderful product for a decent price - the best in its class.My friends and colleagues were pleasantly surprised with the pens (and the FriXion highlighters) when they saw for themselves how well it writes (or highlights) and how well it erases.Pros:-- The ink is smooth, and the erasing is near-complete. Sometimes, the ink may leave smudges, and may not clean completely, but you can use an iron to completely remove it.-- This product is very good for your textbooks, storybooks, and any books that you would want to annotate, yet would want it to remain 'new' after usage. This is especially good for those who would want to resell the books after using in school or college. You can either use the erasing tip at the back of the pen, or what I do is iron the book at a low temperature (higher than the magical temperature of 60 degrees Celsius or 140 degrees Fahrenheit) for quick erase of the book.(May possibly used for borrowed books, but be careful in case things go wrong)-- Good for cross-word or Sudoku.Cons:-- Since the ink is heat sensitive, be VERY careful. Leaving in the car, or a hot day out in the Sun with your notes (in your bag or otherwise) may erase all the written notes using these pens.-- Also be careful if you like to put hot stuff (like coffee) on your notes, because I have absentmindedly done it before, and some of the notes below were gone.-- Although it is supposed to erase the ink, what it does is to change color to transparent at (60 degrees Celsius or 140 degrees Fahrenheit). So what you wrote is still there, and on closer look, you can still see make out what you wrote. Might not be suitable if you don't want others to see what you wrote.-- Not recommended for sewing because it changes color to transparent through heat, and the residue gets left behind on the cloths/clothes. (ie. it is still there, just that it is now transparent, and I am not sure if it is washable)Conclusion:Overall a great solid product for a decent price. Just don't be careless of the heat, and what you don't want others to see.

This is my third pack of Frixion pens- I got the ultra-fine points, a pack of multiple colors, and now a basic set of black fine tipped pens. so I'm amassing a little collection. The thing is, I really do love these pens.Way back in the 90's, I used erasable pens constantly for note taking and writing in college/grad school. They were a beast back then (the ink sort of blobbed onto the paper as opposed to flowing, it smudged all over, and the erasing was moderate at best). Even though I'm not in school anymore, I still like to write long-hand, but somehow the *presence* of an eraser makes it easier for me just *write* and not be indecisive about everything I put down on paper.I heard about these FriXion pens on a web site and I *had* to try them. Flowing LIQUID gel-ink and a true eraser without all the crumbly/smudgy stuff? I needed to try and see if it were true.It is indeed true. These are true liquid ink pens (not ballpoint) that flows from the barrel smoothly. And it erases SUPER cleanly. The ink is heat-sensitive so it it removed via heat, and not the actual material of the eraser. So the eraser on the pen is more like a tool for making heat (hence the friction) and nothing that is rubbed onto the paper.The penbs are great, except for a few things:- the ink is really a dark grey color. It's NOT completely opaque, it's almost translucent grey. If you like that super-inky-black color, this is not a good pen for you.- every time you use the pen, you have to put a good deal of pressure on it for the ink to flow. So the first few marks you make will be either super light/scratchy or not show up at all.- You really do need to write with a little bit of pressure to get the ink to keep flowing. So it's not as easy as writing with a regular gel pen.- the eraser is on the area of the pen you'd cover with the cap when the pen is open, which makes no sense to me.- the point is a little scratchy and my handwriting looks a little bit "shaky" writing with it. It's not as smooth as some other pens I have used, but a general quality of a fine point pen is a tiny bit of scratchiness so it's par for the course, I guess.finally, and this can be a pro or con-the ink in these pens are completely heat sensitive. I just hit it with my heat gun for a quick second (used for crating) and the ink disappeared instantly. Pretty cool to watch (it's like in a spy movie!) but if you are doing a project where you need to apply heat in any shape to your materials, the marks from this pen will disappear. I'm excited about the way I can use this in my art projects.All in all, these are super cool pens, and the best erasable pens I have ever used. I wish they sold a bottle of this ink so I could use it in more applications.

been using these since 5th grade and I graduate college this year, they are comfortable to hold, write and erase well, and once the ink runs out the refills are 6 bucks for a pack of 3 that will last many months

I use these with my Rocketbook and they work pretty well. The ink is not as smooth and flowing as other pens. It erases well though. I have used as a pen on plain paper and again, the ink flow could be stronger but they work.

When you have an office job that requires ink quills these are the best of the best for pen to paper. So smooth and no wet ink on th paper like my 2nd favorite Pilot pens G-2's, tossed all of them. I am not using rocketbook anymore but I need to write fast as my DR offices call in orders fast and I need a ink pen that can do that.
